摘要： Highland vegetables play an important role in meeting the demand for fresh vegetables in summer and also increasing the income of farmers in upland areas of China. With the large-scale and intensive development of vegetable planting in upland areas, many of the farmers have used vegetable-maize rotation instead of the traditional maize monoculture pattern. The bacterial community and diversity under different planting patterns and elevations were investigated using next-generation sequencing and Biolog Ecoplate. The average well colour development (AWCD) was greater at low elevation and under the vegetable-maize rotation. There were 15 classified bacterial genera related to the elevation and planting patterns. The relative abundance ofAquicellawas significantly affected by elevation andWPS-1_genera_incertae_sedisby elevation and planting patterns (p<.01). At the same time, the only genus that was significantly affected by planting patterns wasAquicella(p<.05). Redundancy analysis (RDA) showed that soilpHand available N content were the main factors influencing the change in soil bacterial community structure in the different planting models and elevation, and the dominant species of soil bacteria wereStreptophytaandAridibacter.
